$ dpkg -l | grep ntp
$ dpkg -l | grep timesyncd
rc  systemd-timesyncd                  245.4-4ubuntu3.1                      amd64        minimalistic service to synchronize local time with NTP servers

Title:
  ubuntu_ltp_syscalls failed to run on Focal s390x, unable to restart
  systemd-timesyncd.service

Status in ubuntu-kernel-tests:
  New
Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  Issue found on 5.4.0-34.38 s390x LPAR / zVM

  We need to stop timesyncd for the following tests:
  ['leapsec01','stime01','settimeofday01','clock_settime01']

  But it looks like when we're trying to restart it:
     systemctl start systemd-timesyncd

  It will fail with:
    Failed to start systemd-timesyncd.service: Unit systemd-timesyncd.service is masked.

  
  This issue did not happen on 5.4.0-33.37, the ubuntu_ltp_syscalls test can finish with that kernel.
